Trinidad Pro Series Lopez Type 4 darts are 95% tungsten and the cuts, outlines and weight were improved from the previous model Lopez type 3. The large diagonal cuts for left rotation were changed to alternately semicircle cuts, becoming optimal for any grips and any angles. As a result, this barrel reduces missed shots and transmits force more uniformly. Moreover, this model gains stability due to its 20gm weight, which is 1gm heavier than the previous type. At the same time, its versatility for gripping allows you to use rear-grip, center-grip, and both left and right rotations.
